This might sound silly to some, but for a while now I’ve thought of NGE as almost “biblical”, like in the way it layers and intersperses meaning and symbolism throughout deeply personal stories, told under the auspices of world-ending cataclysm.

Nah, it's not silly. I'm a Christian, and End of Evangelion made me reckon with the Second Coming and the end of all things (more the second than the first) in a deeply affecting way that I can't compare to many other experiences.
